SPINDLE SUPPORTING AND DRIVING DEVICE.

SPECIFICATION forming part of Letters Patent No. 566,847, datedSeptember 1, 1896.

Application filed December 14, 1895. Serial No. 572,144. (No model.)

To all whmn it vita-y concern;

Be it known that I, J ()SEPH DUFFY, a citizen of the United States,residing in Paterson, Passaic county, and State of New Jersey, haveinvented certain. new and useful Improvements in Spindle Supporting andDriving Devices for Spinning-Frames; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to letters of reference marked thereon, which form a part of thisspecification.

The object of my invention is to provide a support for duplex spindles,having the bolsters capable of a slight rocking motion toward and fromthe driving means and also of a slight vertical motion with regard tothe spindle-rail for the purpose of producing a uniform frictionalcontact between the whirl and the driving means.

The invention consists in the improved support for duplex spindles, itsrocking bolsters, in the flexibly-mounted supports for said bolsters,and in the combination and arrangements of the various parts thereof,substantially as will be hereinafter more fully described, and finallyembodied in the clauses of the claim.

In the accompanying drawings, Figure 1 is a front elevation of myimproved support, certain portions being broken away and others shown insections; and Fig. 2 an end elevation of Fig. 1, with the spindle-railand driving-belt in section.

In the said drawings, (t represents the spindle-rail, provided atcertain intervals with openings in which are mounted the threaded ends bof the bearings 12, secured to said rail by means of the nuts b and bypreference with interposed elastic washers F1 The bolsters c" c aremounted on the tube 0 and extend with their downward projections c 0into and through enlarged openings to of the rail. Each end of said tubeterminates in a trunnion cflresting in the bearings b, above referredto. An oil-chamber 0 projects upwardly from the middle part of tube 0and communicates through the latter with the oilchambers of the bolstersin the well-known and usual manner.

In the bolsters c and their projections c are mounted the spindles c,having the whirls d, to which motion is imparted from the traveling beltf; or the said whirls may be provided with pulleys operated throughbelts in the ordinary manner, as will be manifest. A spring g is securedto the spindle-rail a, by means of a screw g, and bears with its upperend against the upper portion of the oilchamber, so as to keep thewhirls d in continuous uniform frictional contact with the drivingmeans.

By simply tightening or loosening the screw g, the tension of the springg can be regulated. I do not intend to limit myself to the use of thespring g, as other equivalents may be used without departing from thespirit of my invention.

\Vhat I claim as new is- 1. The combination with the rail and with thedriving means, of a rocking oil-tube provided at each end with atrunnion, bolsters mounted on said oil-tube, a spindle in each of saidbolsters, a separate and independent bearing for each of said trunnionsadj ustably mounted in the rail, and means for controlling saidoil-tube, substantially as and for the purposes described.

2. The combination with the rail and with the driving means, of arocking oil-tube provided at each end with a trunnion, bolsters mountedon said oil-tube, a spindle in each of said bolsters, a separate andindependent bearing for each of said trunnions flexibly mounted on thespindle-rail, and means for controlling the oil-tube, substantially asand for the purposes described.

3. The combination with the rail and with the driving means, of arockingoil-tube provided at each end with a trunnion, bolsters mounted on saidoil-tube, and projecting into and through enlarged openings in the rail,a spindle in each of said bolsters, a separate and independent bearingfor each of said trunnions adj ustably and flexibly mounted in the rail,and means for controlling the oil-tube,

substantially as and for the purposes described.

4. The combination With the spindle-rail and with the driving means, ofa rocking oiltube provided at each end with a trunnion, an oil-chamberprojecting centrally and upwardly from said oil-tube, bolsters mountedon said oil-tube, a spindle in each of said bolsters, a separate andindependent bearing for each of said trunnions flexibly and adj ustablymounted in the rail, and a Hat spring bearing with its upper portionagainst said oil-chamber and adjustably secured with its lower portionon the spindle-rail, substantially as and for the purposes described.

5. The combination with the spindle-rail and with the driving means, ofa rocking oiltube provided at each end with atrunnion, an

oil-chamber projecting centrally and up- Wardly from said oil-tube,bolsters mounted
